Examining the aftermath of the Louisville bank shooting: CTE, heroics, and mental health.

The father of Connor Sturgeon, the gunman behind the Louisville bank shooting, has confirmed that his son will be tested posthumously for Chronic Traumatic Encephalopathy (CTE) due to his history of concussions. Sturgeon, who suffered from "mental health challenges," opened fire with an AR-15-style rifle in a first-floor conference room, killing five executives at the Old National Bank. The motive remains unclear, but new details continue to emerge about the man behind the attack.
